ConversationList: Show replied/forwarded status

[casasfernando]

What Happened

After replying or forwarding an email message, there is no indication of this action next to it. Other email clients will add a status icon next to the message after replying or forwarding it so the user know that one of these actions was taken with the message.

I found this https://github.com/elementary/mail/issues/37 from 2019 that is already closed, but it seems it was not implemented in the new Mail app for Odin.

Expected Behavior

After replying or forwarding an email message, a "replied" or "forwarded" icon is added next to the message so the user knows that one of these actions was taken with the message.

Steps to Reproduce

1. Select a message from Inbox
2. Reply or forward it
3. No indication that either of these actions were taken is available.
